Replying to Light meter question

hey iv got a question for harvey and the other experienced photographers on this site, i dont mean to get off topic, but i shoot photos for a bunch of skiboard companies, so i know what im doing. But i just had a camera donated to me, and the light meter had me a little confused, on the left side it had shutter speeds starting at like 2 and at the top was 1000, you cant change the shutter speed manually, but it does coincide with the fstop changes you make, for example, if you change your fstop depending on the light situation the red light inside will go up or down on the scale. My problem is, i dont know where to keep the red light at! some people have told me between 125/250 is a good bet, but im not sure. Anyone with a camera with this light meter? any advice would be helpful,
